Definition: (noun) - In art, an armature is an underlying, unseen, supporting component (usually of wood or metal) for something else. Armatures are useful in sculpture, lost-wax casting (to help make the initial model three-dimensional) and even stop-motion animation puppets.
Think of the chicken wire frame upon which plaster or papier mache strips are affixed in a sculpture, to get a mental visual. An even more dramatic example, designed by Alexandre Gustave Eiffel, is the iron armature inside the Statue of Liberty.
